The primary somatosensory cortex generates a late, lateralized positive component (P4) of the human laser-evoked potentials (LEPs)

Session - Poster Abstract Presentation: no. PH 334AIM OF INVESTIGATION: Brief radiant heat pulses, generated by infrared laser stimulators, excite selectively skin nociceptors and elicit a number of transient EEG responses (laser-evoked potentials, LEPs), related to the activation of type-II Aδ mechano-heat nociceptors and spinothalamic neurons. When stimulating the hand, the largest LEP deflections form a biphasic negative–positive wave (N2–P2, maximal at the scalp vertex and central distributed), peaking at ...link_to_OA_fulltex
